Plesielephantiformes is a proposed suborder of the Proboscidea, the group containing elephants and their close relatives. It was named and circumscribed in a 2001 study by Jeheskel Shoshani and colleagues to include Deinotheriidae, as well as Numidotheriidae and Barytheriidae.[1] While originally proposed to represent a monophyletic clade, based on the supposed unifying character of having bilophodont teeth,[1] most modern phylogenetic studies of Proboscidea find the group to be paraphyletic, with Deinotheriidae more closely related to Elephantiformes than to other supposed members of the group.[2]
